Left ventricular noncompaction (LVNC) is believed to represent an arrest in the normal process of myocardial compaction, resulting in persistence of both hyper-trabeculation and intratrabecular recess within the left ventricle. High mortality is the important clinical feature of this disease. LVNC in adult cases has been rarely, but occasionally, reported, however, LVNC with insufficiency of both the aortic and mitral valves has not been reported to our knowledge. Herein, we describe a 62-year-old man with LVNC and the severe insufficiency of the aortic and mitral valves, who was successfully operated upon with aortic and mitral valve replacement using mechanical valves. Although the postoperative course was uneventful, careful attention is mandatory for the possible left ventricular dysfunction due to LVNC.

Primary cardiac malignant lymphoma (PCL), which is defined as an extra-nodal malignant lymphoma involving only the heart and/or pericardium, is extremely rare. Its prognosis is reported to be very poor because the PCL grows rapidly and frequently causes fatal heart failure or arrhythmias. We report a 65-year-old woman with PCL accompanied with superior vena cava (SVC) syndrome 6 weeks following a pacemaker implantation for complete atrio-ventricular block. She underwent a partial resection of the tumor to release the SVC syndrome and subsequent systemic chemotherapy. This combined therapy successfully induced complete remission, and improvement of the atrio-ventricular conduction disturbance was also observed.
